Well I’ve been fixing a computer for awhile, and it just seems like problem after problem.Considering I can only fix it every other weekend and when I am, I have no internet access to diagnose problems… So… The hard drive is totally clean, no OS or anything on it. I Set the BIOS to Boot from CD, first and saved it. When I put in any Bootable CD-ROM into the CD-ROM drive I get the Invalid System Disk error. I have tried it with Multiple CDs, Trying to boot setups and Linux Live OSs(I have tried 2 WindowsXP disks, 1 Slax, 1 Gentoo and 2 Ubuntu). What should I do? Is the CD-ROM Drive broken?
